Summary:Acromioplasty is a well accepted technique recommended for treatment of rotator cuff disease. Arthroscopic acromioplasty can accomplish the same surgical result with less morbidity and be performed on an out-patient basis. The technique here described consistently achieves an acromioplasty which converts a pathological acromion into a Type I, or flat acromion, releases the coracoacromial ligament and allows inspection and access to the acromio-clavicular joint. Techniques of controlling bleeding during the procedure are also described.
